Specification of Letters Patent. I application filed July 16, 1912. Serial No. 709 756.

Patented Nov. 3, 1914.

To all. whomit may concern:

Be it known-'that I,'I -IUeo. Scrruennrn, a subject of the King 'of Saxony, residing at 3 Metzerstrafisa; Rombach, Germany, have 'invented certain new and useful Improverolls, because it was necessary to await the complete delivery and lifting of the rolled the. delivery-trough.

considerably.

materialfon to the cooling bed after each pass before being able to allow the material rolled in the next following pass to enter The present invention has for its object to enable a rolling mill to be utilized to its full capacity by providing the cooling bed with'two or more feedway's which can be charged and discharged independently of eachother. By this means it is possible to increase the-output of the rolling train. very Several;forms of apparatus constructed according to this invention are iill'ustrated by way of example in the accompanying drawings in which:

Figures 1 to 4 are sectional end elevations each showing one form of the improved apparatus. Fig. 5 is a side elevation to 2 of the feed ways: Fig. 5 is a cross section thereof. Fig. 6 is a sectional end elevation of a somewhat different relative dis-- position of the cooling bed and the feed ways showing a form the operation of which is. the same as that shown in Fig. 2.

In Fig. 1. as also in the following figures, a and a are two feed ways constructed in the usual manner as live roller beds for the straightening bench c; r and r are the live rollers of the feed ways. 'w' is the material which is handled by the feedway a, and 1.0 is the material which is handled by the feed way (L The transference of the material 10 from the feed way a is effected .in the usual manner by a conveyor rake t which is raised and lowered and at the same time moved to-and-fro by one or more eccentrics 3. The said rake lifting the material from the feed way a on to the draw bench and at the same time conveying the material'lying on the straightening bench to the cooling bed k' andconveying them farther along the latter.

The conveyance of the material 10 arriving on the second feed way a is efiected in the form shown in Fig. 1 as follows: I; is a tilting a xle actuated by worm gearing s or otherdn'ving means from amelectric motor or other engine. On this axle b is mounted a fork g which lifts the material w from" the feed way a over-the feed way a tothe straightening bench c of the lateral cooling bed is whence the said materialis conveyed away together with the material w by the conveyer rakes it, while the fork 9 moves backinto its original position. The basic idea of this operation is thus a tilting of the feed Way a or rather of the forks g which constitute its sections over the feed way at around the tilting axle b. The shape of the forks is determined by the operation.

The material remains at rest until almostthe end of the tilting movement and then it slides. down the inclined arm g of the fork and is directed into its proper position by the projecting beak g of the forks. 1

The entire arrangementis very The'feed ways are on the-same levele, and their rollers 1" and r are mounted on== the same axis, being driven by a common rol1erdriving device.

ple

In the modification shown a Fig. 2 the a mechanism for transferring the material w to the coolin ,bed is similar to that shown in Fig. l. T ematerial istransferred from the feed way .a by the following apparatus. The lever 12, which is driven by the'c'fankid and is guided by a radius rod f describes with the blades 2' attached to its end a closed curve Z, so that the material w is-lifted by, the blades from the feed way a -and conveyed over the straightening bench a At this place it is removed from'the blades by the strippers m during the return movement and conveyed to the straightening bench. In this apparatus the feed ways may be arranged in step-fashion as shown in Fig. 2, for the purpose of afiording a free path for the movement of the blades. The rollers r and 1* (see Figs. 5 and 5") when driven by a common driving device-have different diameters but equal, peripheral speeds, this can be easily effected by suitably proportioning the bevel gearing p and p;

The strippers m which may also be forked,

are so connected to a lever 5 driven by a cam 4, that as soon the rakes t begin their elevating stroke the said strippers move under the straightening-bench, ready to resume.

L pensed with. The material 20 is lifted by a rake as in the other forms shown, the said rake having a greater up-and-down movement than in Fig. 2. I In the form shown in Fig. 3 the lifting of the material an is effected by lever mechanism 'u, pivotin on a center 9 and adapted to be temporarily inclined by means of-the intermediate parts a, w, y by crank mechanism 2 to such an extent as to allow the material to slide off the mechanism a, on to conveyer levers 6 over the feed way a, whereupon it is stopped by stops at on the straightening-bench c. In this case also the stops dip under the straightening-bench during the stroke of the conveyer rakes t, while the conveyer lever 6 is being raised.

In themodification shown in Fig. 4 the materials w and 10 have a common delivery trough '2 but they are kept strictly apart by double-coiled live rollers r so that each of the two materials 107,10 has its own feed way a, a respectively. The lifting of the material 10 on to the cooling bed It is eifected by the blade device 71 which is (described above with reference to Fig.12gl o erated by means of guide link motion i with the only difference that the curve Z is an open curve and therefore the blades follow the same path in coming as in going.

I clann:

A mechanical cooling bed for rolling mill trains, comprising a plurality of feedways for the rolled material, and means by which said feedways can be independently char ed and discharged, the rolled material being passed by said means .from said feedways to said cooling bed.

2. A mechanical cooling bed for rolling mill trains, comprising a plurality of feedways for the rolled material, a cooling bed alongside of one feedway, and a tilting lever-mechanism by which the rolled material is transferred from one feedway over the other to the cooling bed.

3. A mechanical cooling bed for rollin mill trains, comprising a plurality of fee ways, a cooling bed sidewise of one feedway, a straightening bench and a tilting lever-mechanism for transferring the material from one i'eedway over the other feedway to the cooling bed and straightening bench.

4. A. mechanical cooling bed for rolling mill trains, comprising a plurality of feedways, a straightening-hem alongside of one feedway, a tilting lever-mechanism whereby the material is conducted from one feedway over the second feedway to the straightening-bench, a cooling bed, and vertically and horizontally reciprocating conveyer-rakes alongside of the straightening-bench and cooling bed.

5. A mechanical cooling bed for rolling mill trains, comprising a plurality of feedways for the rolled material, said feedways being independently charged and discharged, a tilting lever-mechanism by which the rolled material can be -lifted from one feedway to the cooling bed, and strippers for removing the rolled material from said gilttling lever-mechanism onto said cooling In 'testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
